Khalid Abdi 06810f861e backend: make docker compose host ports configurable
Mirror the existing POSTGRES_PORT override for the backend, frontend and adminer
host ports (BACKEND_PORT / FRONTEND_PORT / ADMINER_PORT) so a port clash on
`docker compose up -d` can be fixed via .env without editing the compose file.
Documented in .env.example and the README.

# --- Database -------------------------------------------------------------
# When running via docker compose, "db" is the Postgres service hostname.
# For running the backend directly on your host, use localhost:5432.
DATABASE_URL=postgres://temetro:temetro@db:5432/temetro
# --- Better Auth ----------------------------------------------------------
# Generate a strong secret (min 32 chars): openssl rand -base64 32
BETTER_AUTH_SECRET=replace-me-with-openssl-rand-base64-32
# Public base URL of THIS backend (used for auth callbacks & cookies).
BETTER_AUTH_URL=http://localhost:4000
# Directory for uploaded patient/lab files. Defaults to ./uploads in local dev;
# in Docker it's a persistent volume (see docker-compose.yml).
UPLOAD_DIR=./uploads
# --- AI ------------------------------------------------------------------
# Key used to encrypt at-rest AI provider API keys (per-user, set in the app's
# Settings → AI). Generate one: openssl rand -base64 32. Rotating it forces
# users to re-enter their provider keys.
AI_CREDENTIALS_KEY=replace-me-with-openssl-rand-base64-32
# --- App ------------------------------------------------------------------
# The frontend origin — used for CORS, Better Auth trustedOrigins, and the
# links embedded in verification / reset / invitation emails.
FRONTEND_URL=http://localhost:3000
PORT=4000
NODE_ENV=development
# Host ports docker compose publishes. Change any that are already in use on
# this machine (the services still talk to each other on their internal ports).
POSTGRES_PORT=5432
BACKEND_PORT=4000
FRONTEND_PORT=3000
# --- Patient wallet relay -------------------------------------------------
# The URL baked into the QR a patient scans to import their record. Their phone
# must be able to reach it — so localhost will NOT work from a real device. If
# unset, the backend derives it from the request host (fine when you open the
# web app over your LAN IP, e.g. http://192.168.1.20:3000). Otherwise set it
# explicitly to a phone-reachable address: your machine's LAN IP or a public
# tunnel URL.
# PUBLIC_RELAY_URL=http://192.168.1.20:4000
# --- Email (optional) -----------------------------------------------------
# If SMTP_HOST is unset, emails (verify/reset/invite) are printed to the
# server console instead of being sent — zero setup for local development.
# SMTP_HOST=smtp.example.com
# SMTP_PORT=587
# SMTP_USER=
# SMTP_PASS=
# SMTP_FROM="temetro <no-reply@temetro.local>"
